The buoys are preferably formed with a cylindrical central section 36' and with conical ends 37; this construction being suiicient to cause the buoys to always present one ofv the conical ends to the oncoming waves. i

lThe manner of operation of my wave pump is substantially as follows:

In the position illustrated in Fig." l, the waves are presumed to be traveling from beyond the pump inward, the buoys being alined in the direction of movement of the waves and the intakes 13 being positioned as above ,described -ina fixed manner.

Due to the wave action vthe floats are given a rising and falling ymotion and hence operate the cross head which in turn reciprocates the pump plunger. On the upstroke water is sucked. in through'the intakes and through the check valves and on.

the downstroke is forced through the pump valve, being lifted on the neXt stroke, thereby after the pump has been properly primed, continuously pumping vwater as long as the wave action is suflcient to lift the vfloats in relation to the pump barrel.

ln the manner of mounting ythe pump as .shown it is presumed that the waves will travel in substantially the same direction, that is,-lengthwise of the pier or staging illustratedl in Fig. l and hence the buoys will not be required to swivel laterally to a great extent as in many localities the direction of the waves is substantially constant within afew degrees one way or the other; however, if the pump were mounted in a place in which the direction of the waves had considerable change the supporting structure should vbe such as to allow the buoys to swivel or turn to a considerable extent before the stems 82 would contact withV the supporting structure.

Although my invention is of a simple construction and as illustrated shows only one pump delivering water, nevertheless, it is apparent that a battery comprising a number of pumps could be installed and discharged through a common discharge pipe. Moreover, the construction of my pump may beconsiderably changed in general construction and in specific` details to adapt itk to dilerent types of installations. Such changes would be within the spirit of my invention as set forth in the description, drawings and claims.

Having described by invention, what I claim is l. A wave pump comprising in combination a pump barrel having an intake in a seaway, the upper end of the barrel being positioned above the water level, a cap for the upper endy of the barrel, a pump plunger operating through the cap, a cross head rigidly secured to the upper end of the plunger, a pair of stems ldepending from the oppcsite sides of the cross head, the said connection allowing slight rocking movement, a buoy secured to each stem, a collar connecting the buoys, the collar being adapted to slide ,on the pump barrel, a lift valve on the lower end of the plunger and a check -valve in the pump barrel adjacent the inlet, there being a discharge outlet from the pump barrel above the water level,

2. A wave pump as claimed in claim l, in which the stems are secured to the cross head by ball-shaped nuts to allow the rociol ing movement and the floats are constructed with a cylindrical body and tapering ends adapted to maintain the floats head onto a sea.V

3. A wave pumpcomprising in combination a pump barrel formed of a tube, a disc having a sleeve threaded on the lower end thereof, the said disc having a port therethrough, a ball seated in the port and a cage to retain the ball, thereby forming a checlr valve, means to secure an inlet to the lower end of the sleeve, a "l" secured to the upper end of the /pump barrel, a discharging water duct connected to one branch of the T, a pipe section connected to the branch of the T opposite the pump barrel, a cap having an opening therethrough secured to the pipe section, a pump plunger operating through the cap having a lift valve at the lower end, a cross head rigidly secured to the upper end of the plunger, a plurality of stems connected to the outer ends of the cross head, such connection allowing slight rocking movement, a pluralityv of buoys connected to the lower ends of the stems and a collar connecting the buoys, the collar being adapted to slide on the pump barrel.

ln testimony whereof I have signed my name to this specification.
